LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 320,919, dated June30,1885.

Application filed August 24, 1883.

To aZZ whom it may concern.-

Be it known that I, CORNELIUS FALVEY, of the city of Norwich, county ofNew London, and State of Connecticut, have invented certain new anduseful Improvements in Loom- Shuttles, which improvements are fully setforth and described in the following specification, reference being hadto the accompanying drawings.

This invention relates to loom-shuttles for weaving cotton and woolenfabrics. The object of the invention is to overcome the tendency of thefilling to strip from the bobbin when the loom is worked at an unusualrate of speed, and this is accomplished by the means hereinafterdescribed, and particularly pointed out in the claim.

In the drawings, Figure 1 represents a side elevation of a shuttleembodying my invention, a portion of the side being broken away to showthe relative arrangements of the several parts, and Fig. 2 represents asimilar view of the same with the'spindle raised.

Much trouble has been occasioned in mills heretofore by the irregularspeed of the main shafting, especially in mills which are run bywater-power. In such mills the stopping of a portion of the machinerytends to increase the speed of all that remains running, causing suchmachinery to move at a higher rate of speed than is practical or safe.Then the shuttle of a loom is traveling atthe augmented speed thusproduced, and is suddenly stopped in the shuttle-box at either side ofthe loom, the momentum and the sudden stopping causes the yarn to slideforward and away from the bobbin. Thus the contents of the bobbin arewasted, and before the stripping of the filling is noticed a quarter ofa yard or more of cloth may be woven and spoiled.

It is the object of my invention to obviate this objection, which isaccomplished by the means hereinafter specifically set forth.

The letter Aindicates the shell of the shuttle, which is of the ordinaryor any approved (No model.)

abuts against the pin a, so as to permit the spindle and bobbin to shootforward when the shuttle is suddenly stopped, and thus obviate thetendency of the bobbin to strip, overcoming the objections consequentupon such stripping. The spring after the spindle has thus shot forwardreturns it to its normal position. The said spring G at its rear bearsagainst the rear end of the spring F, which is connected to the rear ofthe spindle by means of ascrew, F. The spring F near its forward end isbent upward, as indicated by the letter h, so as to sit in the recess 0in the head of the bobbin and hold it in place while the spindle is in anormal position. The letter h indicates a pin passing over the spring F,near its forward end, against which said spring bears when the spindleis thrown up, as shown in Fig. 2, so as to release the end h from thebobbin.

Having thus described my invention, what I claim is- The combination,with the shell of the shuttle, of the spindle having alongitudinallyslotted shank, the pin to which said spindle is pivoted,and the spring surrounding the shank and abutting against the pin, thespring F, and the pin h, substantially as described, and for thepurposes set forth.
